Abstract

Susceptibility of herbivorous mites to insecto-acaricides.

Abstract

Herbivorous mites do not cause significant damage in apple orchards of Moldova under normal conditions, because their abundance is controlled by natural enemies. However, damage caused by herbivorous mites increases after intensive treatment with insecto-acaricides, which kill the useful acarifauna. The Moldavian Research Institute for Plant Protection and Ecological Agriculture has conducted a monitoring programme on the effects of insecto-acaricides on herbivorous mites since 2000. Data on toxicity of the insecto-acaricides Neoron [bromopropylate] and Omait [derivative of sulfurous acid], for different populations of hawthorn spider mite [Amphitetranychus viennensis], are summarized. The problem of emerging resistance to insecto-acaricides in mite populations is discussed.
